I think this was added for 2 reasons. 1. Drive away hat chasers like blueh said. 2. Cause idiots complain towers are too hard. Now to fix these is get rid of the 1k hat rule, most people will not go as far as 5k to get a hat. And idiots who complain towers are too hard just don't try hard enough or have no experience on the game. And even with new towers i'm just seeing the same guilds dominate. Idiots who complain about them being too hard will never go far no matter how easy towers become to take. Player made guilds have survived and made it far with the normal towers, they didn't need any changing.
